<P>PROBLEM TO BE SOLVED: To provide an opening/closing device in which an increase in the number of parts is suppressed and enabling a reduction in installation space by reducing the size of the opening/closing device. <P>SOLUTION: A second pulley 28 is installed rotatably around a pivot shaft 37. Teeth 38 are formed on the second pulley 28. Deep groove parts 42 engaged with the teeth 32b of a timing belt 32 are formed in the second pulley 28 between the teeth 38 adjacent to each other. A through-hole 43 passing through toward the pivot shaft 37 is formed at the bottom part of the deep groove part 42. Contact tooth parts 32c formed integrally with the teeth 32b of the timing belt 32 pass through the through-hole 43. A piezo-film 44 in contact with the contact tooth parts 32c is stuck on the outer periphery of the pivot shaft 37 partially in the circumferential direction. Consequently, the size of the opening/closing device can be reduced to reduce the installation space while suppressing an increase in the number of parts forming the opening/closing device of an opening/closing body for a vehicle. <P>COPYRIGHT: (C)2007,JPO&INPIT |
